Answer:

$14.93

Step-by-step explanation:

If the cost is per inch, then we need perimeter otherwise if the cost was per square inch we would have looked for the area.

Total cost=circumference* cost per inch

Circumference of a circle is given by

C=2\pi r

Where r is radius. Substituting 4.75 inch for r then

C=2\pi\times 4.75=29.857142857142\\C\approx 29.86 inch

Cost=29.86*0.50=$14.93

Help. only questions 3 & 4 .

I'm doing 3

     For 3, using a table is very similar to a double number because the numbers are matching up in both ways.

         On the bottom of a double number line we have like, for example,-- the bottom of the double number line would have batches. And its 1, 2, 3 ,4 , etc.

         And on a table, it would be the same, the numbers on both diagrams have the same methods, have same way of lining things up but they're just drawn differently.

                Hope this helped!

(secx)dy/dx=e^(y+sinx), please help me solve the differential equation. Thanks :)
nalin [4]
First, you must know these formula  d(e^f(x) = f'(x)e^x dx, e^a+b=e^a.e^b, and d(sinx) = cosxdx, secx = 1/ cosx

(secx)dy/dx=e^(y+sinx), implies  <span>dy/dx=cosx .e^(y+sinx), and then 
</span>dy=cosx .e^(y+sinx).dx, integdy=integ(cosx .e^(y+sinx).dx, equivalent of 
integdy=integ(cosx .e^y.e^sinx)dx, integdy=e^y.integ.(cosx e^sinx)dx, but we know that   d(e^sinx) =cosx e^sinx dx,
so integ.d(e^sinx) =integ.cosx e^sinx dx,
and e^sinx + C=integ.cosx e^sinxdx
 finally, integdy=e^y.integ.(cosx e^sinx)dx=e^2. (e^sinx) +C
the answer is 
y = e^2. (e^sinx) +C, you can check this answer to calculate dy/dx
